To allocate physical interfaces to VDC from the config terminal mode type the VDC name and then allocate the physical interfaces as shown below by using the command “allocate interface”

N7000-ITKE01#configure t

N7000-ITKE01 (config)#vdc VDC-CORE1

N7000-ITKE01-DC-CORE1 (config-vdc)#allocate interface  Ethernet1/1

N7000-ITKE01-DC-CORE1 (config-vdc)#allocate interface  Ethernet1/2

N7000-ITKE01 -DC-CORE1 (config-vdc)#allocate interface  Ethernet1/3

Now let’s verify the Interface allocation to the VDC by using following command ” show vdc membership”

N7000-ITKE01-DC-CORE1# show vdc membership

vdc_id:2 vdc_name: DC-CORE1 interfaces:
        Ethernet1/1           Ethernet1/2           Ethernet1/3          
        Ethernet1/4           Ethernet1/5           Ethernet1/6          
        Ethernet1/7           Ethernet1/8           Ethernet1/9          
        Ethernet1/10          Ethernet1/11          Ethernet1/12         
        Ethernet1/13          Ethernet1/14          Ethernet1/15         
        Ethernet1/16          Ethernet1/17          Ethernet1/18         
        Ethernet1/19          Ethernet1/20          Ethernet1/21         
        Ethernet1/22          Ethernet1/23          Ethernet1/24         
        Ethernet1/25          Ethernet1/27          Ethernet1/29         


In addition to interfaces other physical resources such as IPv4 router memory, IPv6 router memory, port-channels, SPAN sessions can be allocated to individual VDC.
